Top Building Materials Why Cell Phone Signal Reception is Bad

Posted by on Jan 15, 2018

Some of the reasons why you might be experiencing really bad cell phone signal in your home include distance from the cell phone tower, overcrowded cellular towers and outdoor obstructions and low battery. In the case of low battery, a smartphone that is draining power does not have strength to carry out critical functions such as guaranteeing a quality and reliable signal. External obstructions that interfere with cell phone reception include tall buildings themselves or billboards, high mountains or hills and natural vegetation like trees.

Here's the list of top building materials causing your cell phone signal reception to be bad and getting worse. We have the solution: Consumer cell phone signal boosters and Commercial cell phone signal boosters. We provide Nationwide installation service.

Sometimes the cellular signal is overcrowded by such factors as concerts, festivals and other high number of cell phone users jam-packed in a specific space. As thousands of people compete to access the 4G LTE or 3G data speeds, the signal weakens leaving behind a really low internet speed and dropped calls. Crowded metropolitans with very few cell towers usually experience this unique problem. While these are some of the reasons you're probably experiencing a low cell phone signal in your home or place of work, that is not the whole truth. It is highly possible that building materials may be the reason your cellular reception is atrocious. Here're the top building materials why your cell phone signal reception may be bad and getting worse.


Top Building Materials Why Cell Phone Signal Is Bad.

Insulating with fiberglass mostly around attics and building walls does the job perfectly but has an effect on the cell signal. While fiberglass reduces the cellular reception by -2dB, drywall worsens the situation where the loss rises to -4 dB. By the time the cell phone reception enters your home, it has been reduced by 50 percent.

Clear glass.

A modern home with crystal clear glass is great at letting in natural light into your home, including heat. Clear glass also gives you a wonderful view of the outdoors, such as a view of a snowy evening, summer colors and activity. However, if you expect to successfully make a call while close to a clear glass window or door you should think again. Chances are the clear glass is the reason you cannot enjoy a quality data speed or voice call quality. The material can actually refract the cell phone reception by about -4dB.


Metal building materials are heavily used in building construction across North America and around the world. Iron, brass, aluminum, steel or copper among others also have a strong cell phone signal blocking effect of between -32dB and -50dB. Buildings with metal roofs are also heavily affected; metal is a conductor that distorts cellular signals and radio frequency reception indoors.

Cement and concrete.

Clearly, like metal, concrete and cement is a reality of every construction job. Robust, strong and long lasting structures are made with these materials. Even so, concrete and cement to about six inches reduces the cell phone signal anywhere between -10dB and -20dB.


Brick buildings are widely loved for their unique design and strong aesthetics. Made of shale, cement or clay, the modern brick building material might be aesthetically unique and robust, but heavily obstructs cell phone reception by -8dB to -28dB.

Plaster wall coating.

From ceilings to building walls, plaster is a unique protective coating material made of cement, gypsum or lime. As important as it is in construction, plaster actually shuts out cellular reception by -8dB to -16dB.


Solid wood is a superb building material from walls, ceilings, furnishings to doors. Whether maple, beech, mahogany, oak or ash solid wood actually blocks cell signals by -5dB and -12dB with the thickest wood the best at shutting out the cell signal.

Plywood on the other hand reduces cell signal by anything between -4dB and -6dB. Wet plywood is actually worse as it acts like a cell signal sponge reducing the cellular reception by -20dB.

Tinted glass.

Both low-e glass and tinted glasses are wonderful building materials due to their energy efficiency. By ensuring heat is kept out the building is superbly air conditioned. However, they are also notorious at interfering with the cell phone reception by -24dB to -40dB.

Cell phone signal strength.

The closer your phone is to -50dB, the stronger the signal strength. Building materials are important and critical in construction but reduce the signal strength keeping you far from full bars or close to the required -50dB. You might not be living in a dead zone yet (-120dB) but these building materials could be denying you a much reliable cell phone signal whether you're at three bars or -90dB.

You can however surmount these problems and raise the signal strength further to full bars as you enjoy 4G LTE and 3G data speeds and clear voice calls by using a cell phone signal booster for homes and buildings.

Why building material won’t really matter.

Once you have chosen a cell phone signal booster you won’t need to worry about cellular signal problems. The cellular signal is taken from the outside via a high quality cable to enhance the indoor signal. Since the outdoor signal is usually available and calls can be made from the antenna position, you will never worry again about low data speeds and dropped calls. The external antenna will be installed on the building’s roof with the cellular signal booster installed inside the building to avoid damage by the elements. The antenna on the roof will be injecting the cellular signal from the outside and directing it inside the building. It is then picked up by the cell phone reception booster and spread around to all the cell phones and mobile devices inside the living space.

Signal booster for every building size.

Cell phone signal boosters are varied and available for every building size and building type. The selection of optimum performing cell phone signal boosters range from Eqo 4G for small spaces of up to 1,200 square feet, Connect 4G for 5,000 square feet to Wilson Pro 4000R for large indoor spaces of up to 150,000 square feet. There's definitely a cellular signal booster for any type of space that works with all cell phones and cellular service carriers that boosts weak signals to 3G and 4G LTE super speeds.
